My invention relates to ring spinning frames. It is an object of my invention to provide means for preventing the formation of double ends by kinking of two threads, particularly in the case of comparatively long threads.

It has already been proposed to obtain more uniform threads similar to those of ring spinning frames, by increasing the distance between the calender roller and the spindle points which has recently been extended to about 500 millimetres. In their transport across such a distance the threads owing to the rapid motion and rotation are liable to oscillate and to kink so that double ends will form.

It is an object of my invention to eliminate this drawback. To this end I provide channel guides intermediate the calender roller and the spindle point for separating the threads.

The guiding channels may have any suitable form and may for instance be of circular, curved, or polygonal cross-section, as desired. Ridges or partitions'can be provided intermediate the channels to keep the threads apart. The threads Will strike the partitions but they can never jump them to form double ends.

The channels combine into a plate at the rear of the frame which must not extend as far as the calender roller as it is necessary that the calender roller and the parts below same should be readily accessible in case of breakage of threads or other trouble. lVith the channeled plate extending as far as the calender roller these parts would be inaccessible. The necessity of providing this clearance requires provision to be made for preventing the formation of double ends at this point. Such provision is made by auxiliary channels which are arranged in reversed position relative to the channels in the plate, that is, with their openings facing the rear end of the machine, and are adapted to be readily removed. They may be subdivided into separate units which may be supported on an existing shaft of the frame or on a shaft provided for the purpose so 214,334, and in Germany September 20,1926.

that they can be moved out of required.

In order to facilitate the observation of the threads, the sidewalls of the channels in the plate the open sides of which are facing the front end of the machine and are visible from such end, are painted in light colorsso that they reflect light onto the thread between them. Thebottom of each channel, on the other hand, is painted in a color contrasting with that of the thread, for instance, black for white threads, so that the thread is plainly visible. I

In the accompanying drawing a ring spinning frame equipped with my improved channels is illustrated diagrammatically by way of example.

In the drawing Fig. l is a front end elevation,

Fig. 2 is a cross-section Fig. 3 is a section 011 the line III-III in Fig. 1, on a larger scale.

Referring now to the drawings, f is one of the uprights of the frame, a is the calender roller, Z) are the spindle points and g are eyelets. The distance between the roller and the points should be considerable for the reasons set out above. a is a channeled plate which is secured in front of-the upright 7, and a channel d is formed in the plate for eachthread c. The channels are shown with substantially circular sections but, as stated above, the section may be as desired. The side walls of the channels are. combined into ridges or partitions e. The lower end of the plate a extends into the vicinity of the eyelets g and its upper end is at such a distance below the calender roll a that the clearance. provided permits ready access to the parts below the'roll, and the roll itself, in case of trouble. These parts are not shown. If desired, the plate a may be subdivided into any number of units. 7

The clearance between the roller (1 and the upper end of the plate or plates n is bridged by auxiliary channels 7t which are arranged in reversed position with respect to the principal channels cl of the plate or plates at, that is, their open sides face the rear end the way as of the frame, and

of the frame. The channels hwhich extend partly intothe channels (Z are secured to arallel bars 2' and arms is ca *ried to rock on a shaft Z, but held against axial displace- ,ment on the shaft.

It will appear that, with the auxiliary channels it extending partly into the principal channels (Z, short tubular passages will be formed at the ends of each pair of channels but otherwise the principal channels (Z are open toward the front, and the auxiliary channels it are open toward the rear.

The auxiliary channels it are subdivided into units, each unit comprising six'channels in the example illustrated. Axial displacement of the units on the shaft Z must e prevented as otherwise the auxiliary with Fig. 2 shows the auxiliary channels, or one unit of such channels, drawn back in dotted lines in order to expose the clearance between the upper end of the plate a and the roller a, for the purpose specified.

In order to facilitate the observation of the threads, the lateral faces cl of the principal channels (Z are painted in light colors so that the threads are illuminated, and their bottoms are painted in a color contrasting with that of the thread. T he area painted in this color, for instance, black for white threads, is indicated at m in Fig. 1.

I wish it to be understood that I do not ,desire to be limited to the exact details of construction shown and described for obvious modifications will occur to a person skilled in the art.

I claim 1. A ring. spinning frame comprising spindles, a calender roller, a plate arranged intermediate said spindles and said roller, having channels formed therein which are open toward the front end of the frame and defining a gap intermediate the upper end of said plate and said roller, and auxiliary channels extending across said gap, and arranged so that their open sides face the rear end of said frame.

2. A ring spinning frame comprising spindles, a calender roller, a plate arranged intermediate said spindles and said roller, having channels formed therein which are open toward the front end of the frame and defining a gap intermediate the upper end of said plate and said roller, and auxiliary channels extending across said gap and partly into the channels of said plate.

3. A ring spinning frame comprising spindles a calender roller, stationary guiding channels for the threads intermediate the points of said spindles and said calender roller, and movable auxiliary channels intermediate said staionary channels and said calender roller, said auxiliary channels being arranged in reversed position with respect to said stationary channels.

4. A ring spinning spindles, ing channels for the threads intermediate the points of said spindles and said calender roller, and movable auxiliary channels intermediate said. stationary channels and said calender roller, said auxiliar channels being combined into a plurality or independently movable units. 7 v

5. A ring spinning frame comprising spindles, a calender roller and guiding channels for the threads intermediate the points of said spindles and said calender roller, the sides of said channels being painted in light colors, and the bottoms of said channels being painted in a color contrasting with that of the threads.

In testimony whereof I aflix my signature.
